Overview

Computational analysis demonstrates building-specific accidental eccentricity calculations for general multistorey structures, indicating improved seismic assessment under torsional ground motions.

Key Points

  • Formulate and evaluate analytical procedures for quantifying accidental eccentricity and torsion in general multistorey buildings subjected to rotational ground motion without relying on simplified single-storey assumptions.
  • Developed two frameworks: an equivalent static procedure that calculates storey-level accidental eccentricity and a response history analysis accounting for multiple triplets of torsionally coupled modes.
  • Numerically evaluated both frameworks using models of five ten-storey buildings with varied plan layouts and horizontal setbacks subjected to suites of recorded horizontal and torsional earthquake ground motions.
  • Demonstrated reliable calculation of building-specific accidental eccentricity across diverse multistorey structural geometries without invoking special class torsionally coupled building assumptions.
  • Enabled explicit quantification of storey-specific accidental eccentricity for equivalent static procedures and multimodal dynamic response tracking during response history analyses.
